Application filed October 2, 1918., Serial No. 793,017.

To all whom, it may concern Be it known that I, JOSEPH H. Moons, a citizen of the United States, residing at Mulberry, in the county of Polk, State of Florida, have invented certain .new and useful Improvements in Flexible Elbows; and I do hereby declare the following to-,be a full, clear, and exact descri tionof the invention, such as will enable others skilled in the art to which it appertains'to make and use the same. i This-invention relates to pipe joints and has special reference to a pipe joint adapted to be used in connection with a pipe the provision of a pipe joint of elbow, the joints being so arranged as to per mit theswiveling of the elbow about either of the straight pipes.

The principal object of the invention is to. improve the general construction of devices of this character.

A second object of the inventingl resides in t is character in which means formed integral with the elbow and swiveling members are employed whereby inward and outward move ment of the latter under the influence of passage therethrough of 'fluid' under pressure will be resisted.

A third object of .the invention is to provide a joint of this character with a suitable liner.

With the above andothe'r objects in view the invention consists in novel details of construction and combination of parts hereinafter fullydescribed,

- illustrated in the accompanymgdrawings and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views; and Figure 1 is' a side elevation of a oint constructed in accordance with this invention. Fig. 2 is a section therethrough showing the parts in assembled position. Fig. 3 is a detail view ofonehalf of the joint casing or elbow. Fig. '4 is.

a detail side ele ation of one of the revolv p r V spa'e'w ll be'leftbetween the body of they the elbow so that ing membera'or )ipe connections. Fig; 5 is a detail view 0 rig. 6 is a detail'side the split bearing, rings.

In the present embodiment of the inven-'.

-provided with a lon the two flanges encral of certain the liner used herewith.-

elevation of one of flan e 12. This internal flange 12 is wlu gt is pre erably termed the guide for the revolving pi e. At,.the center of the convexportlon 0 each half is a seen-circular opening 13 which registers with x the opposite half so -that when the two halves are glaced together the, openingal8 form'a han hole which suitable hand hole plate 14, saidplate belng secured in position by which engage in a flange around-gthe hand hole. Each of the halves of this, elbow is itudinally extending flange 16 and these an es gether by suitable boltsl a; suitable ac mg (not shQWn being interposed" wee or the purpose of rendering water and air tight. Each of the members consists, of a short cylinortion 17 which has on its inthe Joint swiveling driqal gipe ner en a flan 18. is furt ermore provided a third which is spaced from the flange ll) to provide a lubricating space. The outer end of each of these vided with a flange 20 for the purpose 0 attach ng a straight pi e or making connection/to any desired uid conveyin means.

a second flange 19. There is It will be obvious that in place of t e flange connection 20 the ordinary screw connection may be used but it is not deemed necessary here to illustrate such a screw connection as the same is well known in the art and is commonly interchangeable with the flange connection.

The flanges 18 and 19 are arranged so that, when the device is assembled, they lie on opposite sides of the flanges 12 and between the. flange 18 and the respective flanges 12 are interposed the brass washers or wearing lates iKdica-ted at 21 and each consisting 0 two similar halves connected by'a Z joint 22. It is tojbe noted that by reason of this arrangement,.. when. the sections .17 are inserted in place in the elbow,

sections and the wall of ackings 23 may be placed in this space and 'eldrin position therein by means of suit are bolted ange 18 and spaced from-this sections is furthermore romaybe closed by. a

suitable- .1191159? 15 able lands '24 of the ordinary type;-it bei note that'br'ass washers 25 are inter-pose between the inner-end of the'packing's and theflanges 19. This device furthermore is 'provided with a liner 26 which fits' the central portion ofthe elbow and is ofsuch shape and dimensions to form a continua tion of the side Walls of the pipe sections 17. This liner 26 is furthermore provided with an opening 27 in the concave portion ol the liner so that access may be had to the interior of the joint through the hand hole 13. Extending through the tlang'cs 12 arc the oil holes 28 and the rings 21 are furthci more provided with oil holes 29 so that oil passing through the holes 2% an ll()\V through these rings. The flange 1%) ol each of the pipe sections 1.7 is likewise provided with oil holes 30 so that the ring 25 adjacent Said flange may be pro 'ierly lnhriig-atial. In assembling the device the onohall ol' the elbow proper is laid in convenient position and, the rings .21 having been placed on thijoints 17, the joints are placed in position with these rings lying on opposite sides of the respective flanges 12. The rings 1'3 are then placed in posittion and slipped into the recess formed between the respective joints l7 and the body of the elbow. The other portion of the elbow is then placed on the first portion and the packing inserted and the two bolted firmly together by the bolt 17. The glands then being placed in position and the packing inserted the same is tightened up by the proper adjustment of the gland bolts.

It is to be noted that by means of this construction a joint capable of standing very heavy pressure is obtained since any tendency of the pipe joint 17 to move out of the elbow is resisted by the tlangc In of such a joint and furthermore in the case of suction pipe any tcndenm ot' the respective joint; 17 to move inward is resisted by its flange 19. There has thus been provided a simple and ellicicnt device of the kind dcscribcd and of the character specified.

It is ohvious that many minor changes may he made in the form and construction of this invention without departing from the material principles thereof. lt is not therefore desired to confine the inwntion to the exact form herein shown and described, but it is Wished to include all such as prop erly come within the scope claimed.

Having thus described the invention, what is claimed as ncw, isz-- pipe connrction comprising a body diridcil longitudinally into rompicincntar sections. means for uniting said Ht'llnlm in aswiiililcd relation. internal llangcs spaced from the respective ends of sa d sci ons and :ll'illiljl'ttl to l'orni continuous flanges when the sections are assembled. pipisections each having spaced. llan Jcs at its inner z-nd embracing thc rcspcciivc continuous IlHtIfL'tS. said pipe sci-L on being: l'nrtlicr providcd each with a third flange spaced from the first mentioned tlangrcs on said pipe sections, said pipe ections having body portions spaced l'roin l'lnbod) St't'll llb to l'orin pachin; spat-cs. glands niovablc on the pipe sections to cntcr ilnpacking spaces. and parliin; hold bctwrcn the third llangc oi each pipc suction and its gland.

In testimony whereof, I aliiX my signzp t-urc. in the prcscnce of two witness s.
